Question

2A. Referring to their structure, please describe three examples of how molecules in the extracellular matrix help protect tissues from different types of mechanical stress or damage B. There are no known motor proteins that move on intermediate filaments. Suggest an explanation for this observation. C. EDTA is a small molecule which binds to divalent cations and prevents it from being used by proteins. When added to epithelial cell culture, EDTA can promote the dissociation of tissue structures into individual cells. Please propose a reason for this observation. -A - Myosin takes roughly 71nm per "step" as it moves along actin filaments. D. Suppose that: What is the rate of ATP hydrolysis during this movement in #ATP molecules hydrolyzed per second? Please show your work for full credit. ATP/second

Explanation / Answer

1.

Three examples of how molecules in the extracellular matrix help in protecting tissues from
different types of mechanical stress:

The extracellular matrix act like a structural scaffold.
They provide adhesion to the cells.
As they are formed of different fibers, they form a net like structure which hold the tissue together.
